[texts]Development and Simulation of Mathematical Modelling of Hydraulic Turbine
Power system performance is affected by dynamic characteristics of hydraulic governor-turbines during and following any disturbance, such as occurrence of a fault, loss of a transmission line or a rapid change of load. Accurate modelling of hydraulic System is essential to characterize and diagnose the system response. In this article the mathematical modeling of hydraulic turbine is presented. The model is capable to implement the digital systems for monitoring and control replacing the convent...

[texts]The Nokia and Samsung Brand Personality in China*
The purpose of this paper is to study and compare the brand personality of Nokia and Samsung in Chinese situation for brand building reference. This paper investigated Nokia and Samsung brand personality. Results demonstrated that Nokia brand personality has four dimensions (Sureness, Reliability, Agility, Peacefulness), and Samsung has three dimensions (Competence, Sophistication, Agility). The absence of Ruggedness supports the implication of many studies that Ruggedness is a culture-specific ...

[texts]Algorithm for Modeling Unconventional Machine Tool Machining Parameters using Artificial Neural Network
Unconventional machining process finds a lot ofapplication in aerospace and precision industries. It ispreferred over other conventional methods because of theadvent of composite and high strength to weight ratiomaterials, complex parts and also because of its high accuracyand precision. Usually in unconventional machine tools, trialand error method is used to fix the values of processparameters. In the proposed work an algorithm which isdeveloped using Artificial Neural Network (ANN) is propose...

[texts]Mass Transfer Studies on Fluidized Bed Adsorption Column for Phenol Adsorption - Sunil J. Kulkarni, Ravi W. Tapre
Mathematical modeling for removal of Phenol using fluidized bed adsorption from the wastewater has been presented in thiswork. Present experimental study deals with effect of initial concentration of phenol and particle size on the rate of adsorption. Thefluid and solid phase mass transfer coefficient at various mass of phenol in the solvent per unit mass of adsorbent were found in wellagreement with well known mathematical models...

[texts]Non‐Linear Reaction‐Diffusion Process in a Thin Membrane and Homotopy Analysis Method
The system of non linear reaction‐diffusion process in thinmembrane describing steady state of chemical reactions thatinvolves three species is discussed. The equations arecoupled by the non‐linear reaction terms with mixedboundary conditions. A closed form of an analyticalexpression of concentrations for the full range of enzymeactivities has been derived using Homotopy analysis method.A simple form of an approximate analytical expression ofconcentrations in terms of dimensionless parameter...

[texts]Economic Load Dispatch Problem with Valve – Point Effect Using a Binary Bat Algorithm
This paper proposes application of BAT algorithmfor solving economic load dispatch problem. BATalgorithmic rule is predicated on the localizationcharacteristics of micro bats. The proposed approach hasbeen examined and tested with the numerical results ofeconomic load dispatch problems with three and fivegenerating units with valve - point loading withoutconsidering prohibited operating zones and ramp rate limits.The results of the projected BAT formula are compared withthat of other techniques ...
